CREAT-GONE FOR CREAM-SEPARATORS.

Application filed September 28, 1917.

To all whom it may concern:

Be it known that I, PERLEY L. KIMBALL, a citizen of the United States,residing at Bellows Falls, in the county of Windham and State ofVermont, have invented a certain new and useful Tmprovement in Cream-Cones for Cream-Separators, of which the following is a full, clear, andexact description.

The object of this invention is to provide aneffcient means forregulating the density of the cream produced by a centrifugal creamseparator of the cone or disk variety of liner or skimmer.

The invention consists of a cream cone having a constricted orcontracted neck provided with a vertically arranged pocket, theeffective area of which is variable by means of a horizontally arrangedadjustable screw plug, above which is a lateral opening communicatingwith the pocket and the exterior space for the discharge of the cream,as l will proceed now to explain and nally claim.

Tn the accompanying drawings illustrating the invention, in the severalfigures of which like parts are similarly designated, Figure l isavertical section of a cone and part of a cover of approved construction,the cone containing one form of the invention. Fig. 2 is a cross-sectionof the neck of the cone of Fig. l, taken at right angles to the sectionin that figure. Fig. 3 is a top plan view of portions of Fig. l.. Fig. 4is a top plan view and Fig-5 is a side elevation illustrating amodification.

The cover l and the body of thefcone 2 may be of any usual, approved orpreferred construction. The cone 2 has a neck 3, the upper internaldiameter of which is constricted or contracted in any suitable way, asby a ring 4L applied thereto in any suitable permanent and immovable wayand of a thickness suitable to receive a vertically disposed recess 5extending from its bottom nearly to its top. This recess is in the formof an inverted pocket, and is herein referred to as a pocket, it beingclosed at its top by a solid portion 6 of the ring 4 and open at itsbottom, as clearly shown in Figs. l and 2, thus forming a cream passagecapped or closed at its top. Near the bottom of the pocket is ahorizontal or lateral screwthreaded hole 7 in which is placed the solidcream regulating screw plug 8. This screw Specification of LettersPatent.

plug may be turned so as to more or less fully in order density of thecream. A horizontal hole 9 1s arranged in the neck above the screw plugand communicates with the pocket and the exterior of the neck, for thepassage of the cream. The neck of the cone may be provided, in alinementwith the pocket, with a block 10 made with or permanently and immovablyxed to the neck and standing off laterally therefrom sufficiently tofill, fully or otherwise, the vertical slot ll in the neck l2 of thecover and fiush with the periphery of the neck, as shown in Figs. l and3, or so as to project laterally beyond it as seen in Figs. t and 5.This block has init continuations of the screwthreaded hole for theregulating screw plug and the cream exit. The block projects as far fromthe center of the bowl as the neck of the bowl is from the center,andpreferably slightly more, so that the "cream shall discharge at a littlelarger circle than the neck of the bowl or cover and thereby in no wayinterfere with its escape into the cream pan free from the neck of thebowl or cover.

As will be understood the internal diameter `of the ring 4 issubstantially equal to the external diameter. of the feed tube used inthe separator, and this tube forms the inner wall of the pocket 5.

By the construction described, the vertical cream passage (pocket 5) hasits top capped or closed above the regulating screw plug, therebyforming a small reservoir or pocket aboveand also outside of the innerend of the screw plug, so that the passage of the cream may be regulatedwith` great nicety. The pocket functions as an open space or pool, intowhich the cream that has been regulated by the inner point `of may bedischarged and thence flow outward through the outlet 9 into thereceptacle outside.

Another important feature of the invention is the provision of a pocketwhich eX- tends beyond the inner end of the screw plug and communicateswith a cream outlet or exit arranged above such plug. This space orpocket is of 'such capacity that when the screw 7 is turned laway fromthe center, there is still left enough capacity for the overflow ofcream that has been regulated, It will be noticed that as the screwapproaches the center of the neck or close the pocket to control therecedes from it the holding capacity of this pocket back of the screwvaries, but there is room enou `h for any adjustment that the 'screw iscapa le of performing.

Another feature of the invention is the provision of the extension-blockor boss l0 made as a fixed part of the neck of the cone, the combinedthickness of the neck and block being suiiicient to bring the outsideface of the block even or flush with the neck of the cover or to extendbeyond it, the cream outlet leading from said pocket through the neckand block as an integer to an exit that is beyond the outer wall of theneck of the cover.

The advantage of having the extensionblock or boss 10 made so that it isintegral is that its inner or extreme outer surface is 'such that itsouter passage shall not be carried through different thicknesses ofseparate concentric necks, one sliding inside of the other, as is thecase with some makes of cream regulating devices which have been on themarket for some time. In such devices the holes in the different partsas these are assembled, are supposed to come in exact alinement, but dueto inaccuracies in drilling the holes in the different parts, and afterthey are worn, these holes do not exactly aline one with the other.There is an oiset or corner, and there is a ridge of cream between thewalls due to this inaccuracy of alinement. With the boss or extensionblock of the present invention, the passage is solid all the waythrough, and there is no chance for non-alinement or leaky joints.

Variations in details of construction are considered as within the scopeand principle of the invention.

Vhat I claim is z- 1. A cream cone for centrifugal cream separators,having a neck provided With a ring having a vertical pocket closed atits top, an extension block arranged on the outside of the neck inalinement with the pocket, a screw plug arranged in a screwthreaded holein the block and neck and adapted to be projected more or less into(lopies of this patent may be obtained for the pocket, and a creamoutlet passage also extending through the block and neck and into thepocket above the screw plug.

2. A cream cone for centrifugal cream separators, having a neck providedwith an interior ring, said ring having a vertically arranged recessclosed at its top and open at its bottom, and a screw plug arrangedhorizontally in the neck near the bottom of the recess and adapted to beprojected into the recess to restrict its effective area for the passageof the outgoing cream Without altering the capacity of the upper portionof the recess, said recess provided near its upper end with' a creamexit.

3. A cream cone for centrifugal cream separators, having a contractedneck provided with a recess closed at its upper end and open at itsbottom, a laterally extending block on `the outside of the neck inalinement with the recess and provided with a cream exit extendingthrough it and int-o the closed end of the recess, and av screw plugarranged in a hole extending horizontally through the block and neck andinto the recess below the cream exit.

Al. A cream cone for centrifugal cream separators, having a contractedneck provided with a recess closed at its upper end and open at itsbottom, a laterally extending block on the outside of the neck inalinement with the recess and provided with a cream exit extendingthrough it and into the closed end of the recess, and a screw plugarranged in a hole extending horizontally through the block and neck andinto the recess below the cream exit, combined with a cover having aneck provided with a slot into which the block extends so as to deliverthe cream free of the neck.

In vtestimony whereof I have hereunto set my hand. this 26th day ofSeptember, A. D. 1917.
